WORK-HOLDING STAND.

Application tiled. July 26,

To all whom t may concern:

Be it known that I, ROBERT CrRUs LEE, a

rico and State of Virginia, have invented certain new and useful Improvements in TWork-Holding Stands, of which the following is a specifieation, reference being had therein to the accompanying drawing.

My invention relates to improvements in work-holding stands which are adjustable vertically and in horizontal and vertical planes, and. it particularly relates. to stands for holding radiators of automobiles; and it has for its object to provide an adjustable stand in which all automobile radiator may be securely supported and hy Ineens of which .the position of the radiator may loe so changed that .any part or surface of the said radiator may. be presented to the Workman.

This object I attain hy `the mechanisms and arrangements illustrated in the aecompanying drawings, in Whig-zh?I` Figure I shows the stand in elevation, and supporting an automobile radiator; Fig. II is a side View of the stand, and supporting a radiator; Fig. III is an' enlarged detail, partly in section, ci one oi' the .clauupS by which the radiator is supported; Fia 1V is an .enlarged View, partly inv section, of the swivel joint at the head .of the stand. Figs. V, VI, VII, VIII and IX show some of the many positions in which the radiator may be held in the stand. Similar numerals refer to similar parts throughout the several views.

in which slides the vertical rod 3, the height .of which in' the sleeves be adjusted by means of the movable collar d, which is secured by the set-screw 5.

VAt Vthe upper end of the rod 3 is head Y s peeicaton of Letters Patent.

In F igs.' I and II, 1', 1, 1, are the legs of a tripod stand supporting the Sleeves 2 2 Patented J une 1, 1920. 191s. serial No. 246,904.

low. In the top of the head 6 there is a set- .screw 13 which bears upon pressure 'plate 14;, which in its turn presses upon the stud 7. The set-screw and pressure plate form a means of putting pressure upon the stud 7 so as to act as a brake, allowing the stud to be turned in the heady 6, but yet preventing accidental displacement. Positive locking of the stud isquickly accomplished, af-

ter it has been turned into the desired position, by means of the clamping nut 9,

The arm 12 is supported at its middle in the 4clamping jaws 10. Ajt either end the arm is bentat right anglesV to the portion passing through the head 6, the said bent portions being designated in the drawings hy the numeral 15- At the end of the portions 15, l5 the ann is bent upwardly, es at .the Vertical portions ,16, 16, Which portions terminate in the bosses .117, 17. Y

A detail of one of these bosses 17, with the adjustable rod and clamp for supporting the radiator, is shown r-in Fig. III, in which'lS is a set-screw bearing upon a pressure plate 19, which in itisyturn bears upon a bushing 20. This bushing is .collared at one end, yand at the other end extends slightly beyond the boss i7. Through the bushing there passes the .rod 2.1, having the threaded portion 22, on which are mpunted two .clamping nuts 2,3 and 2d, the formerbeing adjacent to the collared `end of the bushing 20, and thelatter adjacent to that lend ,of the bushing which proj eots beyond the boss 17, By manipulating the two clamping nuts 23 and 24 the l lamount oi' projection of the rod 21 through the bushing 20 can be regulated; and as soon as adjusted it is clamped firmly ,in place, relative toV the bushing, by means of the .clamping nuts 23 .and 2d But Athe bushing may yet be free to revolve in the boss 17. The revolution .or ,the .tuebingen ne boss may be controlled by means .of the pressure plate 19 and setserew `18.

Supported lat one end ,of the rod 21 are pair of hinged clamping jaws 25, hinged ,at 2.6. The jaws 25 are pivoted on and secured to the rod l21 by means of the bolt with nut 28K. The .contacting surfaces of the ia-ws 25 and the arm 21 may he rouehened or out in the lSlt-lane ,of .teeth to guard .against accidental .movement should the holt y27 not have been tightened suiiiciently. Y

The upper and lower jaw of the pair of jaws 25 are brought together with pressure by means of the screw 29, which may be pro-V vided at its Vupper end with a small handwheel 30 for quick and easy manipulation.

Referring to Fig. I, it is seen that the radiator is provided with two ears -or lugs 31. This form of ear, projecting sidewise from the radiator, is used in some cases;Y

supported in theV stand.

To ysupport the radiator the screw 29 is slackened, the jaws are separated, the lugs 31 are inserted between the jaws and the said jaws are again tightened by means of the screws 29. As all radiators are not Vof the same width, and as raditor lugs are not at the same distance apart, adjustment of the Y distance .between the two sets of clampingv jaws 25 is necessary, and this adjustment is obtained by means of the threaded portion 22 of the rod 21, with the clamping nuts 23 and 24.

By means of the swivel joint in the stand head 6 and ofthe swivel joints in the arm bosses 17 the 'supported Y radiator may be Vthrown into any position, the vertical height of the Work above the floor being adjusted when necessary bysliding the rod 3 in the sleeves 2 of the tripod stand. In Fig. I the radiator is shown suspended with the radi# ator cap downward, and drain upward. VThe back of the radiator is next to the stand, and the workman would be working on the opposite side, that is, on the face side of the radiator, which would be to the right in 1 Fig. II. Should he wish to work directly on the face of the radiator he simply swings the cap end or top of the radiator upward toward him, securing it Vin position by means of the set-screws in the bosses 17. Should he wish to work on the top face of the radiator he swings the whole arm in a vertical plane about the minor axis of the arm which is the stud 7 in the stand head 6, as indicated in Fig. V. If instead of rotating the arm at the stud 7, the workman throws the radiator into a vertical position by rotating it on the bushing 20, the back of the radiator will be then presented to him,

as indicated in Fig. VI and Fig. VII. Figs.

VIII and IX show how the back or front t maybe presented to the workman with the vertical portions 16 of the arm 12 pointing downward, that is, the arm having been rotated at the stud 7 in the rod head 6.

Many operations have to be performed upon an automobile radiator, in the way of 'Y repairs, and on many different parts of its surface; and the repairing'of a radiator, as usually carried out, takes much time, due to 'the weight and shape of the radiator and the awkwardness inlhandling it. With the radi ator supported in my work-stand it may be quickly swung into and held in any de sired position, so effecting a very large saving of time, reducing the number of tools' and other material required, and leaving the workman free to apply himself directly to the point of repair. Y
